The generic and magic term "panacea" (丸藥 wanyao) used in 1914 was gradually replaced by more specific terms (頭痛藥餅 toutong yaobing). This change in terminology suggests a dual process of rationalization and specialization in medical advertisement. Note that in 1914, headache was more specifically associated to insomnia.
